My new Compak E8 grinder arrived just in time for Xmas. I have no tree and anyway it would not fit under the tree so I took out my sebenza and cut the box open, unpacking and installing the machine. I expect to put 10-20kg through the grinder before really putting it to the test. Jan van der Weel and I have promised a review for KTC magazine to appear in the spring 2016 issue. So there's time!
Below the list of pictures is a video of a first shot of espresso after dialing in the grinder to find the "espresso" grind, aiming for 30g of espresso in 30 seconds from 18g of grinds in the VST 18g portafilter basket, tamped with the LONDINIUM tamper and extracted on the Londinium L1-P lever machine, monitoring the flow with an Acaia Lunar coffee scale.
This specific grinder has the Lucidate "Red Speed Burr" set for lower friction and lower temperature.

Can't really say yet. I just unpacked and installed it. Jan and I will test and review in January. The first shots look and taste great though! I have not even methodically compared R120 and HG One inside-by-side shots yet. Could be nice to even do a ROK / E8 / R120 / HG One compare, measuring extraction % in shots that all were 30g in 30s from 18g. Later.
(also see Daily Coffee News feature ) Tije designed and made the following structure for a tiny and cheap fluid bed roaster, to which Jan van der Weel added the Arduino parts, electronics and programming: Sketch by Tije de Jong Jan sourced a very cheap blower (€ 11) to start with, Tije developed and constructed the mechanics, Jan built together and programmed the TC4 / SSR electronics. On his blog, Jan will specify exactly how the TC4 part is combined and programmed and I will copy these details into this blog entry, just as Jan will use this video in his blog. We did a few test roasts to make sure it works at all and it does. Towards the end, the first roast tended to get a flat BT line and airflow was slightly decreased. 200g seems max load of green beans. Second roast a little more power was given to the heater. Next we will try the Background Roast driven by the PID software of Artisan. A week later, with updated software that works better to change the fan
Delicious cup: all the work was well invested! At the end of the previous blog about the pressostat and PID working together , I mentioned that I would like to clean up the xmas tree of wires and have as few cables and probes as possible to visually disturb the classic design of the La Pavoni. Getting rid of the probe that was fastened with copper tape to the top of the brew group was a priority. I wanted to hide a new probe in the cooling fin as close as possible to the brew group. This morning I asked Tije if he could do that. He would need to drill a straight hole of 3mm diameter in the 4mm inner ring of the cooling fin that sits as a tight clamp around the brew group. Always the optimist, Tije set to work: First, Tije made a piece of aluminum to fit the inside of the ring. Drilling a thin hole straight through the curved aluminum, if possible tangentially going through the inside of the ring to touch the brew head directly, you need the support of the temporary insid
illustration by Matthias Gerstgrasser On the mailing list for Artisan users , Matthias Gerstgrasser posted a report about his coffee roaster project, with a link to a beautifully illustrated, complete step by step guide of his work on Instructables: A while ago I posted a few messages on here regarding automation for my hot-air popcorn roaster, and was asked if I could share a writeup of what I had been doing with my setup. I know it’s been a long time, but I haven’t forgotten, just got a little sidetracked (more on that below). I have finally found time to do this over the last few weeks though, and compiled a step-by-step guide of how I modified my popcorn machine. This is now available on Instructables: https://www.instructables.com/id/Arduino-controlled-DIY-Coffee-Roaster/ Do let me know if there’s anything missing or anything that could be improved. I intend to keep updating the guide as I find ways to improve it or as new developments occur. I am also discussing b
